【摘要】

：

本实验运用行为测量、尿液及包皮腺的GC-MS分析和qPCR测定的mRNA水平表达差异三个层面来探究小鼠社会优势地位及其相关特征的遗传性。我们将C57雄性小鼠两两配对，经过21天的社会争斗建立了稳定的优势从属关系。双项选择测试表明，优势雄鼠的尿液对雌鼠的吸引力比从属鼠强；旷场测试表明从属小鼠表现出更高水平的焦虑；对社会性的测试表明，从属小鼠对陌生小鼠的探究显著减少。

暗纹东方鲀应激逃避的行为及组织学观察

硬骨鱼及两栖类幼体应激逃避的主要方式是快速逃跑行为,即C-start,而Mauthner 细胞(M细胞)则被认为是指导快速逃跑行为的指令性神经元.本研究发现,当暗纹东方鲀幼鱼和斑马鱼受到骤发的声音刺激(100 Hz,110 dB)时,其反应均为快速逃跑.暗纹东方鲀C-start行为的发生概率为23.9t％,较斑马鱼(73.33％)低；暗纹东方鲀快速逃跑反应的延迟时间为11.95土4.90 ms,而

小清蛋白在褐菖触发声肌中的特性

褐菖鲉(Sebasticus marmoratus)，是一种暖温性底层鱼类，它能够利用发声肌快速收缩使鱼鳔振动而产生声音。发声肌是一对附着于鱼鳔两侧的特殊肌肉，因能够快速收缩而被称为超快肌，其形态特征和物理特性均表现出肌肉快速收缩的适应性。最近有研究表明，小清蛋白(parvalbumin)对于发声肌的快速收缩也可能有重要作用，尤其对于发声脉冲间距较长的发声鱼类。
